Using SCSI or IDE as a VMWare virtual device adapter

For a while I noticed the performance of a virtual machine (2 cores, 2GB, Win Server 2K8 R2 64Bit) was very poor, while the autostart services always timed out. After starting services manually things eventuallystarted working although at a sluggish pace. Fixed: changing the VMWare device adapter from IDE to SCSI, the performance has signifincantly improved.
